I don't know if this is a known issue or not, but it does seem like you are hitting a scaling issue.
I am not totally following the test flow here. The Exception logs you gave are coming as soon as mininet starts having trouble (python tracebacks) or only after you issue a logout? I think you also said that you are getting these exceptions after a clean reinstallation of ODL? You mean, after unzipping and starting again you get the exceptions, without even running the mininet test?
